Mapping
animal behavior
|
Grade
Level: 4-6
|
Overview
Biologists need to know about animal behavior to protect endangered
species or control disease or pests. The California Condor was down to
one in the natural habitat and very few in captivity because of the pesticide
DDT being used by farmers. Also the Tule Elk in Point Reyes California
was near extinction until scientists found that these elk needed certain
plants introduced back into the environment containing copper. Scientists
need to know about sampling, animal mapping so that they don't have to
look at every single animal in order to make an inference about a problem.
Purpose
To discover through the use of inference and deduction the
needs and wants of animals. To learn how to carefully observe and record
behavior systematically as the animal moves through its habitat. To learn
about sampling to get statistics for inference. To learn how to graph
and what a graph can do. To learn about caring for and being kind to all
living creatures. To learn about variables.
Objectives
Students will be able to:
|
i. Identify the needs of at least
three animals |
ii. Observe the behavior of some
animals in their habitat |
iii. Care for some animals
Resources/Materials
|
Live crickets - one in ziplock bag
per group. |
Hamsters, gerbils, goldfish can also
be used (In this lesson we will be using crickets.) |
Large boxes - at least 8" X 10" (you
can add paper to sides to make taller so that animal will not jump out).
|
Colored round dot stickers - about
1/2" in diameter - sheet of 80 per group (or small paper made circles). |
Three blank 8 X 10 pieces of paper
for each group. |
1 pencil per group. |
Large clock with second hand (if
available) |
2" X 3" construction. paper for shelter
(folded in a triangle) |
Nuts, cereal, apple slice or bran for food.
Task
cards:
|
Recorder |
Number dots from 1 to 20 - three
times |
Place eyes on dots to show in which
direction animal moves. |
At end of trial describe the animal's
actions. |
After recording for one trial, swap tasks with another team member.
Timekeeper
|
Make sure team members are ready
to start. |
Tell Animal Manager when to place
the animal in the center of box. |
Watch the clock and call "Time!" every 15 seconds for 5 min.(20 times).
Observer:
|
Watch closely where the animal moves.
|
Tell the Recorder in which direction
to place the dots. |
Remind your team members not to disturb
the animal, not to touch it or talk too loudly. |
After observing for one trial, swap tasks with another team member.
Animal Manager
|
Hold the animal or its container
until your team members are ready to begin mapping. |
Put the animal in the center of the
box when Timekeeper says to start. |
Hold the animal between trials. |
Keep the animal from escaping. |
After managing the animal for one trial, swap tasks with another team
member.
Graph paper: Set up so that part of graph paper is to graph trial 1,
part for trial 2 and part for trial 3.
|
Everyone should participate and keep own copy for his/her own science
journal.
Trial 1 - vertical axis Number of dots on Map 0 - 20 across bottom,
write: IN THE OPEN AREA and NEXT TO WALLS and LOOKING IN CORNERS.
Trial 2- across bottom horizontally: IN THE OPEN AREA NEXT TO WALLS,
FACING INTO CORNERS, NEAR OR IN THE SHELTER.
Trial 3, across bottom horizontally: IN THE OPEN AREA, NEXT TO WALLS,
NEAR THE OR IN SHELTER, NEAR OR IN THE FOOD
Activities
and Procedures Read any material you find in library or elsewhere
about the Tule Elk, California Condor, wolf, or any other interesting
animal scientists are investigating. Put on board or large piece of paper
so that all children can view, a large square or rectangle to represent
the classroom. Then have large 1" stickers numbered from 1 - 20 with eyes
on one side. Send one child out of the room for a few minutes while you
explain to the rest of the class that you are going to map the child's
movements when he/she returns. Then have him/her come back. Map in front
of the class on the board or large sheet of paper where he goes in the
room. Every 20 seconds place a sticker with eyes pointed in the direction
he is facing and on the spot on the paper showing his relationship to
the room. Explain that the class will use the same technique to map movements
of crickets.
Assigning team tasks:
|
1. Divide class into teams of 4 students
& give task cards |
2. Explain 4 roles, have them read
task cards aloud, emphasize tasks rotate. |
3. Let teams take a few minutes to
delegate tasks, number the dots and place eyes on dots. |
4. Give box, cricket in ziplock bag to animal manager.
Assign groups
|
1. Explain there will be 3 trials
per cricket. In trial l, box will be empty. |
2. Place animal in center of box,
record movements every 15 sec. for 20 samples. Record movement by taking
sticker and placing it on blank paper eyes facing correct direction, in
corresponding location to the place in the box. If animal jumps out of box,
put it back where it was and continue. |
3. In trial 2 box will have shelter. Fold a rectangular piece of construction
paper to simulate a shelter. Follow same steps as trial 1. Look at your
paper. Did the animal act differently now that there is a shelter to run
to? Did the animal look at the shelter? What can you 'infer' from this?
Tying
it all together Place graphs from all groups
on the board and discuss each graph and make inferences together as a
whole group. Then have each child record his/her group's findings and
draw a picture about what the cricket in the box did most often in each
of the 3 trials.
Assessment
This is again an activity which involves the class in groups.
During the rap up session, the teacher should take note of the variability
in the presentations. However, the ensuing discussions should enable the
teacher assess the suitability of this activity for use with other grades.
Suggestions/Modifications
|
- The project can be done by the teacher with the students as observers.
- Students should understand the meaning and importance of extinction.
- Students may find out which animals in their area are endangered and
why. They may write letters to local politicians and organizations on
behalf of the endangered animals.
